Well, first we can rule out B and D. When you multiply a positive number by a negative number, you will get a negative number. Since the product of this equation is a positive, we can rule these 2 out. Now we are left with A and C. There are 2 ways you can solve this. You can divide 144 by 16 or 36, or multiply 4 by 16 or 36. I perfer to multiply 4 by A or C. 4 x 16 = 64. So we can rule that one out. SO your answer is C.
Step-by-step explanation:
(3x² + 4x - 8) - (-2x² + 4x + 2)
[3 - (-2) = 5] , [ 4 - 4 = 0] , [ (-8) - 2 = -10]
5x² + 0x - 10
(or)
5x² - 10
Answer:12/18 = 6/9 = 2/3
Step-by-step explanation:
Penny reads 14 pages in 1/3 hour.
In order for us to know the rate of penny, the number of hours per page, we need to do ratio and proportion.
14 : 1/3 = X : 1
1/3X = 14
X = 42
So there are 42 pages Penny can read in 1 hour.
